Don’t fight the dark: Five simple ways to cut down on light pollution

When you visit the George Observatory, you’ll notice signs that say, “Please no white lights.” You’ll also see that all our outside lights are red. The reason we do this is to fight light pollution and create a dark-sky-friendly environment (or at least as dark as we can this close to Houston).

So what can we, as individuals, do to fight light pollution? Here are five simple things:

1. Turn off all unused lightsYour dad was right: leaving lights on when you’re not using them is just throwing money away. So when you leave an area, make it a habit to turn the lights off.

2. Shield all outside lights Outside lights should serve one purpose: to show you where you’re going. So why do so many people insist on lighting the underside of passing airplanes? We encourage you to invest in light shields. They will help with light pollution and save you money.

3. Don’t over-lightWhen installing outside fixtures, consider the best wattage for your needs. You want enough light to see where you are going — anything else isn’t helping you see . Also, your neighbors will appreciate you not flooding their bedrooms with light.

4. Avoid ornamental lightingIt’s wonderful that you’re proud of your home, but remember what we said about light pollution and crime. When you overuse ornamental light, you may feel like your house is more secure; however, you’re actually making your property a target for thieves.

5. Spread the word!Now that you know the dangers of light pollutions, share that information with others. There are many websites that will help you and your friends protect the night sky, like the International Dark Sky Association.

Knowledge is power, and we all need to do our part to keep the stars at night big and bright deep in the heart of Texas!
